Pentesting in Practice. How Penetration Testing Strengthens IT Security


Pentesting is one of the most effective tools in the arsenal of defense strategies against digital threats. In an era where information is the most valuable resource and cyberattacks can lead to catastrophic consequences, penetration testing is no longer an option – it is becoming a necessity. Therefore, in this article you will find all the most important information about pentesting. Discover: what it is, what it consists of, how it contributes to IT security and how to apply it to your business.

Introduction to pentesting: the basics of penetration testing

Pentesting, or penetration testing, is the process of examining information systems to detect potential security vulnerabilities. It is the manual or automated testing of systems and applications to discover weaknesses just as a potential attacker would. During it, they look for security flaws, verify what damage a hacker can cause and whether the system is ready for an attack. Finally, a finished report with conclusions and recommendations is presented. Pentests can take various forms, such as:

  • Web application penetration testing – uncovers unpatched security vulnerabilities, so hackers won’t introduce SQL and Cross-Site Scripting (XSS) code into applications, and Cross-Site Request Forgery (CSRF) attacks will be hindered. Testing avoids loss of customer trust, reputational damage, data breaches and service interruptions,
  • Penetration testing of mobile apps – looks for security gaps and bugs, so you can create a safe space for customers and stop attacks on mobile apps involving, among other things. on malware infiltration or denial-of-service attacks, which can cause privacy, reputational and financial damage,
  • External network penetration tests – prevent network intrusions, data theft, malware attacks that exploit vulnerabilities in external networks resulting from weaknesses in firewalls, routers and other network elements,
  • Internal network penetration tests – prevent potential data breaches, disrupted operations, unauthorized access and reputational damage caused by malware, targeted attacks or insider threats. The tests highlight weaknesses in network infrastructure, misconfigurations and human factors.

Regardless of the area of operation, the goal of penetration testing is always the same – to protect any potential entry for attackers. Pentesting is thus a controlled attack on a customer’s system to assess its security. His job is to find security flaws before hackers do. It’s about understanding the mechanisms that potential attackers can exploit and pre-empting their actions by sealing the system. During pentesting, system components such as MYSQL/SQL database configurations, firewall configurations, web browsers, FTP settings, network applications, wireless network structure or SMTP mail server configurations are checked.

Why is pentesting important for your business?

Digital security is becoming increasingly important in today’s world. The proper functioning of many industries – from finance to healthcare to technology – depends on it. That’s why penetration testing is a key part of assessing and improving digital security.

Pentesting is essential for any organization that takes its digital security seriously. Penetration tests assess an organization’s ability to protect its networks, systems, applications and users from unauthorized attacks. Among the benefits of pentesting are:

  • Positive impact on system security,
  • Ensuring the system’s compliance with regulations,
  • Ensure the confidentiality of data, which affects customer confidence,
  • Preparedness for potential attacks and informed security decision-making,
  • No financial losses due to attacks by cyber criminals,
  • competitive advantage.

Stages of the pentesting process

The first step in the pentesting process is planning and preparation. Pentesters set the goals, scope and conditions of the test. All this is documented and communicated to all stakeholders.

This is followed by a stage focused on recognition. During it, specialists gather as much information as possible about the system under test, which can help them find potential weaknesses.

The third stage is scanning. This uses various tools to identify entry points and other details about the system. The choice of specific tools depends on the specifics of the system in question, the goals of the test and the skills of the pentesters.

The final stage is the actual testing and analysis of the results. Tests are conducted manually or automated, and the results are then analyzed and documented in a report.


Pentesting is an extremely important part of any organization’s security strategy. From identifying vulnerabilities to understanding the risks to controlling your system, penetration testing makes it all possible. No matter how large your enterprise is, pentesting should be an integral part of your security strategy. It’s an investment that may bring little benefit in the beginning, but can provide security and peace of mind in the long run.

When deciding on pentesting, be sure to select the right service provider and thoroughly understand the purpose and scope of the tests. Without the right approach, pentesting may not deliver the expected benefits. So opt for penetration testing and wireless network security audits at Elementrica.
